Swimming is very popular in the world. Most people like swimming in summer, even in the other three seasons. Water makes people feel cool and swimming makes people keep healthy.
If you swim in a wrong place, it may not be safe. A lot of people died when they were enjoying themselves in the water, and most of them were students. Now some people are not careful enough in swimming. They often think they can swim so well that nothing will happen to them in water. If you go swimming in summer, don’t forget that a lot of good swimmers have died in water. They died not because they couldn’t swim, but because of their carelessness (粗心). Don’t get into water when you are alone. If there is a “No Swimming” sign（标记）, don’t get into water. If you remember these, swimming will be safe and enjoyable (舒服的).

【小题1】____ like swimming in summer.

Why should we learn to swim?
Firstly, swimming is a good exercise for our health. Indeed doctors say it is the best exercise, because in swimming all the muscles of the body are used.
Secondly, swimming gives great pleasure. How nice it is, on a hot dusty day in summer, to take off one’s clothes and dive into the cool water of a rive or the sea, and to swim and float until one feels enough.
Thirdly, swimming may sometimes mean all the different between life and death, we never know when we may be in danger from water. We got on a voyage, and the ship in wrecked; we go for a pleasure sail on a lake and the boat turns over; we slip as we are walking along the bank of a river, and half in the water. If we can swim, we have chance for saving our own lives, but if we cannot swim, we are pretty certain to be drowned. So for our own safety, we should learn to swim.
Lastly, if we can swim, we may be able to save other people from drowning. How sad it is to see a friend drowning before our eyes while we cannot help just because we cannot swim.

Dear Tom,

How are you? I'm at a new school this term. And I'm writing to tell you about my school. My new school is big and nice. There are one thousand and four hundred students and one hundred and forty teachers at my school. I like the teachers. They are very kind to me. My classmates are very friendly too. They teach me Chinese and l teach them English There are trees, flowers and green grass at my school. They are very beautiful. Behind my school there is a small river. The water in it is quite clean. We can swim in it. We have no classes on Saturdays or Sundays. Sometimes I play football or basketball with my classmates. Sometimes I stay at home and watch TV. Sometimes I go shopping with my father and mother. We all like China.

Please write to me soon!

Yours,

Jack
